  • Patent number: 11980961
    Abstract: A welding auxiliary joining part with which a welding connection, more particularly a resistance welding connection, can be established between a first component A made of a poorly weldable material and a second component made of weldable material. The welding auxiliary joining part is distinguished by a cylindrical punch shaft that can be punchingly pressed into the first component A approximately rotation-free. The punch shaft has an element head at the head underside of which only one continuous circumferential clamping ring is arranged that projects axially in the direction of the punch shaft.

  • Publication number: 20240139855
    Abstract: An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.

  • Patent number: 11673206
    Abstract: A welding auxiliary joining part is disclosed in the shape of a stud having a head, a shank and a tip. The welding auxiliary joining part is driven in by means of a mechanical-thermal setting method into a component of non- or poorly weldable material. During the driving in, a welding head is created due to mechanical deformation so that the component may be connected subsequently via the welding auxiliary joining part to a further component of weldable material by means of welding.
